Everything British for PBS Viewers to Stream in September 2025
The cooler air is already heading this way, and half the kids I know are back in school; it must be time for September to roll in and the fleeting month the American South gets to call autumn to begin. However, due to an embarrassment of riches, local PBS stations have already begun rolling out the fall lineup, starting with Professor T Season 4, The Marlow Murder Club Season 2, and Unforgotten Season 6, all of which premiered the penultimate weekend of August 2025.
Unfortunately, that makes September's listing a touch awkward. Much like July 2025, which had zero Masterpiece premieres because every show that debuted in June ran until the first weekend of August, this month's list is similarly devoid of Sunday night fare, not because there isn't any, but because all three shows conclude Sunday, September 28. October will be stacked, because no matter what happens, October remains the crossroads of when Award season films hit theaters/streaming and new seasons of TV shows reach full swing.
However, for this September, the debut lineup mainly consists of Walter Presents, mixed with a few new top-of-the-month debuts, and one major return to PBS Passport, which everyone will be happy to see. Let's run down everything arriving on PBS streaming for September 2025.
